Shifters
I presently have a road bike with Shimano STI manual shifters (Brifters), 9 speed, with a two speed, compact, chain wheel and would like to change to a 3 speed chain wheel but of course the present 2 speed Brifter wouldn't shift three speeds. I have two other bikes with three speed chain wheels and I can get a (to me) better range of gears with the three as opposed to the compact setup. The best option, which is also the most expensive, would be to buy a new set of STI shifters, but are there any options? I've been thinking of a friction, bar mounted, front shifter and use the existing STI front shifter only as a brake. Another option might be to use a MTB shifter (click, click, click), which would look a little dorky. Has anyone ever done a conversion similar to this? Did you like it? Are there other options? -- Cheers, John B. |

Your bike store may still be able to get a single left lever to match your existing shifters, or at least a single left lever that will shift a tripple, even if it doesn't match. You can also use a single bar end lever, or a single downtube lever. Some pro drug users did that in the start of the brifter era, when they weren't convinced that a left brifter was worth the weight penality. You miht be able to find a lever used. :Has anyone ever done a conversion similar to this? Did you like it? :Are there other options? I've ridden a bike like this. (It was a buddy's spare, he'd replaced the right (rear) shifter with a bar end after a crash.) The shifters worked fine, but it's a little weird having different shifters. I'd probably have found a bar end for the left less weird, since you don't use it much. -- sig 14 |

There used to be a thing called an "Erickson Gizzmo," a sort of tubular cam device that went inline with the front derailleur cable. It had a small lever you'd rotate to drop to the small chainring. Here are photos from Sheldon Brown's site: http://sheldonbrown.com/images/erickson-gizzmo.jpg from http://sheldonbrown.com/gloss_e-f.html But I imagine it's a pretty rare find these days. Personally, I think I'd just use a bar-end shifter on the left, and use the left STI lever only for braking. Didn't Lance proclaim that to be acceptable? BTW, I wonder if you'll need a new front derailleur as well. Derailleurs for doubles are different than for triples. -- - Frank Krygowski |

The ability to brake and shift in one place is worth some extra bucks. I wouldn't consider down tube shifters again. -- duane |

I probably wouldn't want them in a different place but Bangkok is essentially flat. On a typical Sunday ride I might use two gears on the way out and back (Bangkok does slope very slightly from North to South) and perhaps one more lower gear for the hump backed bridges. I find them quite hand.... particularly when you only shift about 6 times in three hours :-) -- Cheers, John B. |

The bike shops stock what sells. The largest bike shop in Bangkok (two branches and innumerable agents in towns all over the country) no longer stocks wheel parts - hubs, spokes, rims. I asked them about it and they tell me that "nobody buys wheel parts any more". I have been considering adding a single lever shift lever on the L.H. side of the handlebar and see how it works out. :Has anyone ever done a conversion similar to this?

The shifters worked fine, but it's a little weird having different shifters. I'd probably have found a bar end for the left less weird, since you don't use it much. I've been chewing it over and on that bike, in the locality I ride it, I generally don't shift the chain wheel much. I usually put it in "high range" and leave it there until I can't get any further up the hill and than shift to "low range" none of this split shifting - "front down one; rear up three" that I think the English used to talk about. -- Cheers, John B. |

That is sort of interesting. I can make something like that pretty easily. I wonder whether the front shifter is linear enough that it would shift "Low - Middle" with the gizmo on one position and "Middle - High" in the other"? Personally, I think I'd just use a bar-end shifter on the left, and use the left STI lever only for braking. Didn't Lance proclaim that to be acceptable? But I don't have a spare bar-end shifter :-) And, I certainly don't have all the oomph that Lance has/had :-) BTW, I wonder if you'll need a new front derailleur as well. Derailleurs for doubles are different than for triples. Maybe. I've used two speed shifters and they work.... sometimes. -- Cheers, John B. |

It's also not very flat around here. But Jay posted a link for a pretty inexpensive brifter. This seems like the most elegant solution because it seems like the most simple. Not often you can appease William of Occam and your wallet at the same time. -- duane |

It was an in-line mini shift lever for 'one more click'. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
